"Close Encounter: Skyscraper-Sized 'Potentially Hazardous' Asteroid Zooms Past Earth Today"

An 890-foot asteroid named Asteroid 2008 OS7 will pass by Earth on Friday, coming within 1.7 million miles of the planet, and NASA is monitoring it as a "potentially hazardous object." Although not visible to the naked eye, NASA offers a virtual asteroid tracker to observe its path, and the Virtual Telescope Project will livestream the event. This asteroid is one of 18,232 Apollo-classed asteroids and is part of NASA's efforts to study and potentially deflect asteroids that could pose a threat to Earth.
